PR-39 产品活性：PR-39 是富含脯氨酸和精氨酸的天然抗菌肽，是一种非竞争性，可逆和变构的蛋白酶体 (proteasome) 抑制剂。PR-39 可逆地结合到蛋白酶体的 α7 亚基上，并通过泛素-蛋白酶体途径阻断 NF-κB 抑制剂 IκBα 的降解。PR-39 刺激小鼠的血管生成，抑制炎症反应并显着减小心肌梗死面积。 产品来源： https://www.medchemexpress.cn/pr-39.html 研究领域：Metabolic Enzyme/Protease | Anti-infection 作用靶点：Proteasome | Bacterial In Vitro: PR-39, shown to selectively affect proteasomemediated protein degradation in vivo, alters the shape of the 20S and 26S cylinder and affects the binding of 19S caps in a reversible manner. PR-39 specifically blocks degradation of IκBα and HIF-1α by the proteasome. PR-39 (100 nM) blocks TNF-α-induced (1 ng/mL; for 20 minutes) activation of VCAM-1 (2 hours) and ICAM-1 (8 hours) expression in human umbilical vein endothelial cells (HUVEC). PR-39 (10 μM) does not affect the ability to proliferate of ECV304 cell. PR39 is able to inhibit IκBα degradation without significantly affecting overall protein degradation in cells. In Vivo: PR-39 (10 mg/kg, intravenously; 1 hour before Caerulein of 50μg/kg, ip) blocks IκBα degradation and NF-κB-dependent transcription in the mouse pancreas after induction of acute pancreatitis. PR-39 (1 μg/kg/day; 7-day intraperitoneal infusion) demonstrates significantly small infarct in C57BL/6 mice. 相关产品：MG-132 | Rapamycin | Doxorubicin hydrochloride | Bafilomycin A1 | Dimethyl sulfoxide | Dexamethasone | Puromycin dihydrochloride | Staurosporine | Actinomycin D | Bortezomib | Etoposide | G-418 disulfate | Nigericin sodium salt | 5-Azacytidine | Brefeldin A | CCCP | Estradiol | Ionomycin | Hygromycin B | Mitomycin C | Resveratrol | Tunicamycin | Everolimus | Doxycycline hyclate | Tacrolimus | Methotrexate | Streptozotocin | Lactate sodium | Neomycin sulfate 品牌介绍: MCE (MedChemExpress) 拥有数百种全球独家化合物，我们致力于为全球科研客户提供最新最全的高品质小分子活性化合物；10,000 多种高选择性抑制剂、激动剂涉及各热门信号通路及疾病领域；设有专业的实验中心和严格的质控、验证体系；提供 LC/MS、NMR、HPLC、手性分析、元素分析等各项质检报告，确保产品的高纯度、高品质；产品的生物活性多经各国客户实验验证；Nature, Cell, Science 等多种顶级期刊及制药专利收录了MCE客户的科研成果；专业团队跟踪最新的制药及生命科学研究进展，为您提供全球最新的活性化合物；与世界各大制药公司及知名科研机构建立了长期的合作。
